One WhatsApp AI for Text and Voice Messages: Transcription, Translation, and Replies From Your Own Facts

Voice notes are half the reason WhatsApp inboxes don't scale. A text question takes five seconds to read; a 90-second voice note in Portuguese takes 90 seconds if you speak Portuguese. Teams searching for a fix usually phrase it as: "one AI that handles chat and voice on WhatsApp in one place."

Within one honest boundary — voice messages, not voice calls — that exists today. Here's what "handling voice" actually means in WhatsApp AI Pro, and where it stops.

Voice Notes Become Text, Automatically

With voice transcription on, every incoming voice note is transcribed as it arrives — and if the customer speaks another language, translated along with the rest of the conversation. A 90-second Spanish voice note lands as readable English text in the thread, next to the original audio.

That's per-session configurable: the same panel that controls auto-translate and the AI agent has the voice transcription toggle. The Translation tutorial walks through it.

The AI Answers a Voice Note Like Any Text

Once transcribed, a voice note is just a message: the agent reads it, finds the answer in your uploaded company info — catalog, prices, policies — and replies in the customer's language. The same three control modes apply: Auto (replies itself), Suggest (drafts for one-click approval), Watch (transcribes and translates only, you type).

So the customer who speaks their question about price and availability gets the same grounded, accuracy-checked answer as the one who types it. Nothing about your setup forks into a "voice flow" — one agent, one knowledge base, both formats.

Why One Assistant for Both Formats Matters

Tools that treat voice as a separate channel make you maintain two brains: a chatbot for text and something else for audio. Here the pipeline is transcribe → translate → answer from the same knowledge base, which means:

One source of truth. Update your price list once; voice and text answers both change.
One conversation history. The transcript sits in the thread, so a rep who takes over (Team Mode or Enterprise Inbox) reads the whole exchange — including what was said aloud.
One language layer. 90+ languages for text and transcribed voice alike; the reply goes out in the customer's language either way.

What This Deliberately Doesn't Do

No voice calls. It doesn't answer WhatsApp calls, doesn't speak, and isn't a phone bot. Incoming voice messages in, text replies out. If a talking AI that takes calls is the requirement, Respond.io's AI agent takes voice calls on its Growth tier ($159/mo, WhatsApp Business API required) — that's the tool shaped for it.
No voice replies. The AI answers in text. Customers overwhelmingly accept a text answer to a voice question; the reverse (making them listen to synthetic audio) is rarely what they want.
No website chat widget. This is WhatsApp-native software for your existing number — not an omnichannel suite. If you need web chat + WhatsApp + Instagram in one inbox, that's the Respond.io/Tidio shape, on the Business API.

Frequently Asked Questions

Can AI transcribe WhatsApp voice notes automatically?

Yes. With transcription enabled for a session, incoming voice notes are converted to text as they arrive, and translated if the sender speaks another language. The transcript appears in the conversation alongside the audio.

Can the AI reply to a voice message?

Yes — in text. The transcribed voice note goes through the same pipeline as a typed message: the agent finds the answer in your company info and replies in the customer's language, in Auto, Suggest, or Watch mode.

Does it handle WhatsApp voice calls?

No. Voice messages are transcribed and answered; calls are not answered, and there's no speaking bot. For AI that takes actual voice calls, look at Respond.io's AI agent on the WhatsApp Business API.

What languages does voice transcription work in?

The same 90+ language layer as text: the voice note is transcribed, translated to your language, and the reply is sent in the customer's language. No per-language configuration.

Do I need the WhatsApp Business API for any of this?

No. It's a desktop app (macOS/Windows) connected to your existing WhatsApp number by QR code. No Meta verification, no per-message fees. $49/month flat, or $499/year, with a 7-day money-back guarantee.
